Pushing a String, the Border between Classical and Quantum Physics
A century ago a Dutch scientist, Paul Ehrenfest, hypothesized that at the border between the quantum and classical worlds the two sets of laws should match. Evidently, in the simple example of a string pushed across a table top they do not! Why they are different reflects a little of the angst of the quantum world.
